Amine catalyst A1 is mainly used in the production of soft polyether polyurethane foam, and also in the hard foam for packaging. The catalytic effect of amine catalyst A1 on water was particularly strong, so the foam density could be reduced. It controls about 80% of the reactions that produce gases, and about 20% of the reactions that control gels. The catalyst has high activity and low dosage. By adjusting the dosage of this series, the rise of foaming and gelation time can be controlled. The common use of amine catalyst A1 and organotin catalyst can obviously improve the production tolerance of foamed plastics, so as to avoid unnecessary quality problems caused by careless operation or small errors in the measurement system, and to produce high quality soft foamed plastics. Amine catalyst A1 is widely used in various formulations for the manufacture of polyurethane foams, especially for the production of high rebound, semi-rigid foam and low density foams.
